Buck Boswell and his all-girl troupe are stranded in Paris, but Buck manages to con the manager of the 'Hotel de Navarre' in furnishing accommodations for his group, but the proprietor's wife locks them out. In his search for funds, Buck meets Patricia Harper, the fourth-richest girl in the world, but he isn't aware of that and thinks she is penniless. Patricia joins his troupe as a lark, and her father, James Harper, also pretends he is broke. Through some chicanery, Buck gets jobs for the girls as models at the Palace of Feminine Arts at the Paris International Exposition. James Harper borrows the priceless Napoleaon necklace to have a copy made for his daughter, but Buck thinks he stole it.

In his last film assignment, portly Walter Connolly fills the title role (in more ways than one) in The Great Victor Herbert. Very little of Herbert's life story is incorporated in the screenplay (a closing title actually apologizes for the film's paucity of cold hard facts); instead, the writers allow the famed composer's works to speak for themselves. In the tradition of one of his own operettas, Herbert spends most of his time patching up the shaky marriage between tenor John Ramsey (Allan Jones) and Louise Hall (Mary Martin). Many of Herbert's most famous compositions are well in evidence, including "Ah! Sweet Mystery of Life", "March of the Toys" and "Kiss Me Again", the latter performed con brio by teenaged coloratura Susanna Foster. Evidently, the producers were able to secure the film rights for the Herbert songs, but not for the stage productions in which they appeared, which may explain such bizarre interpolations as having a song from Naughty Marietta.
